Abstract

In the semiarid re91on of San Luis Potosi, the mesqu1te woodland 1s considered one of the more 1mportant ecosystems from the soc10-economical and ecological point of vlew Currently exploitation of lhis woodland community occurs with little understand1ng of lhe management consequences Th1s has ímpacted the annual grow rates, and species díversity. Therefore, !he obJective of thIs study was to determine the structure and annual growth rates of mesquite woodlands, thriving under different environmental conditíons. The mesquite woodland stand located in San Lorenzo is the driest of the three sites, with a rainfall less than 300 mm yea(1 , This woodland has qn uneven-age diameter-class distribution, apparently influenced by previous land use changes and particutarly by the harvesting of mature trees. Average growth rate for basal diameter and main branches is O 5 cm year-1 The Veinte de Noviembre and Pozo del Carmen  sites had greater precIpItation (350 - 500 mm year -1 with an average annual growth rate greater than 0.6 cm year -1 . The Veinte de Noviembre sIte had an uneven-age diameter-class dístribution, while the Pozo del Carmen had an enen­age diameter-class distribution. In this ecosystem, the annual growth rate of mesquite woodlands varíes large!y based predominantly on edaphic and precipitation conditlons.
